A specific inoculable affection endemic in some valleys of the Western Andes, in Peru, and characterized by a prodromal febrile period and subsequent outbreak of peculiar pin-head- to pea-sized, or larger, bright reddish, rounded, wart-like elevations. The prodromal symptoms, of an irregular malarial or typhoid type, with associated rheumatic and muscular pains, may last for weeks or several months, usually abating when eruption presents. The lesions may be crowded together in great bunches. The face and limbs are favorite localities. The disease is inoculable and thought to be due to a bacillus. The fatality varies between 10 and 20 per cent. Tonics and stimulants are prescribed. #Equinia.# (_Synonyms:_ Farcy; Glanders.) #What is equinia, or glanders?# A rare contagious specific disease of a malignant type, derived from the horse, and characterized by grave constitutional symptoms, inflammation of the nasal and respiratory passages, and a deep-seated papulo-pustular, or tubercular, nodular (_farcy buds_), ulcerative eruption. A fatal issue is not uncommon. It is due to a micro-organism. Treatment, both local and constitutional, is based upon general principles. #Miliaria.# (_Synonyms:_ Prickly Heat; Heat Rash; Lichen Tropicus; Red Gum; Strophulus.) #What do you understand by miliaria?# An acute mildly inflammatory disorder of the sweat-glands, characterized by the appearance of minute, discrete but closely crowded papules, vesico-papules, and vesicles. #Describe the symptoms of miliaria.# The eruption, consisting of pin-point to millet-seed-sized papules, vesico-papules, vesicles, or a mixture of these lesions, discrete but usually numerous and closely crowded, appears suddenly, occurring upon a limited portion of the surface, or, as commonly observed, involving a greater part or the whole integument. The trunk is a favorite locality. The papular lesions are pinkish or reddish, and the vesicles whitish or yellowish, surrounded by inflammatory areola, thus giving the whole eruption a bright red appearance--_miliaria rubra_. Later, the areolae fade, the transparent contents of the vesicles become somewhat opaque and yellowish-white, and the eruption has a whitish or yellowish cast--_miliaria alba_. In long-continued cases, especially in children, boils and cutaneous abscesses sometimes develop; and it may also develop into a true eczema. Itching, or a feeling of burning, slight or intense, is usually present. #What is the course of the eruption?# The vesicles show no disposition to rupture, but dry up in a few days or a week, disappearing by absorption and with slight subsequent desquamation; the papular lesions gradually fade away, and the affection, if the exciting cause has ceased to act, terminates. #What is the cause of miliaria?#
